detailed introduction: 
1. Optimatly designed bit profile suitable for drilling soft to medium formations and medium formations. 
2. Cutting structure is force balanced and bit blde is asymmetrically designed so that the load on bit is balanced which resulting better stability of the bit. 
3. Multiple types of high performance PDC cutters are strategically arranged on bit for improved serivice life of the bit. 
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers. 
5. Hdraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance claening and cooling effects of the bit to effectively prevent bit from balling.
